54 * The digital-chip EIC controller can support maximum 3 banks, and each bank
60 #define SPRD_EIC_BIT(x) ((x) & (SPRD_EIC_PER_BANK_NR - 1))
64 * The Spreadtrum EIC (external interrupt controller) can be used only in
67 * The Spreadtrum digital-chip EIC controller contains 4 sub-modules:
68 * debounce EIC, latch EIC, async EIC and sync EIC,
70 * The debounce EIC is used to capture the input signals' stable status
71 * (millisecond resolution) and a single-trigger mechanism is introduced
72 * into this sub-module to enhance the input event detection reliability.
